Fixed Inductors

Fixed inductors are electronic components used in electronic circuits to store energy in the form of magnetic fields. They consist of a wire or circuit board coil around a magnetically permeable core, and can provide necessary inductance in circuits. Fixed inductors can be classified according to their winding type or their form factor. One of the most commonly used fixed inductors is the S1008-123J.

S1008-123J Application Field and Working Principle

The S1008-123J fixed inductor is primarily used in power supply and charger circuits, as it is designed to provide an adjustable, stable output voltage. The inductor is also widely used in the filter circuit of the switching power supply.

The S1008-123J is a molded, cylindrical inductor with an adjustable iron core. It is composed of an outer copper coil and an inner iron core. The iron core is a two-part solid structure with a gap in the middle, which can be adjusted according to the output voltage of the actual circuit. The iron core works as a magnetic bridge, connecting the N poles of the external magnetic field and the S poles of the internal magnetic field, thereby establishing an inductive force.

When the external alternating current passes through the outer winding of the S1008-123J, it produces an alternating current in the continuously changing magnetic field in the gap, changing the characteristics of the inductance. By adjusting the gap in the middle of the iron core, the value of the inductance can be changed, and the output voltage of the circuit can be adjusted.

The main features of the S1008-123J fixed inductor are its low profile construction, adjustable inductance, excellent heat dissipation characteristics, and wide operation temperature. It is also highly resistant to interference from high frequency signals.

The S1008-123J fixed inductor is an ideal component for power supply circuit design. Its adjustable design is easy to use and provides an efficient and accurate output voltage, allowing for a wide range of applications.
